Monoclonal Mouse Affinity Purified B IC FC
Eck (EphA2) is a member of the Eph receptor tyrosine kinase family which binds Ephrins A1-A5. A and B class Eph proteins have a common structural organization. The human EphA2 cDNA encodes a 976aa precursor including a 24aa signal sequence, a 510aa extra- cellular domain (ECD), a 24aa transmembrane segment and a 418aa cytoplasmic domain. The ECD contains an N-terminal globular domain, a cysteine-rich domain and two fibronectin type III domains. The cytoplasmic domain contains a juxtamembrane motif with two tyrosine residues, which are the major autophosphorylation sites, a kinase domain, and a sterile alpha motif (SAM). The ECD of human EphA2 shares 90-94% aa sequence identity with mouse, bovine, and canine EphA2 and ~45% aa sequence identity with human EphA1, 3, 4, 5, 7 and 8. EphA2 becomes autophosphorylated following ligand binding and then interacts with SH2 domain- containing PI3-kinase to activate MAPK pathways. Reverse signaling is also propagated through the Ephrin ligand. Transcription of EphA2 is dependent on the expression of E-Cadherin and can be induced by p53 family transcription factors. EphA2 is upregulated in breast, prostate and colon cancer vascular endothelium. Its ligand, EphrinA1, is expressed by the local tumor cells.
